The Columbus metro spreads across several counties, and Union County — about 432 square miles of Ohio — carries its full share of the region's pest pressure.
Union County's pest calendar is the regional one with a local accent: hot humid summers and deep-freeze winters that push pests indoors in waves, and the work concentrates on carpenter ants first, overwintering pests second, and house mice never far behind.
Union County — 432 square miles, centre near 40.30° N, 83.37° W, and the 45th largest of the state's 88 counties by land — belongs to the Columbus metro alongside 9 other counties. Local providers cover it from that metro, licensed under Ohio rules.
Union County sits roughly 36 miles northwest of Columbus. Its 432 square miles make up about 9% of the land in the metro's county footprint, which places it a mid-sized county for this metro. For pest control, position is practical information: routes, response times and even the dominant pest mix shift across a metro this size, and Union County's slot in it — its distance from the core, its share of the metro's land, its own balance of dense streets and open ground — is the context every local inspection starts from.
